【発明の詳細な説明】 自動車用の操縦ハンドル 技術分野 本発明は、自動車用の操縦ハンドルに関し、特に操縦ノ）ンドルのリム及びスポ ーク、そのハブ上に互って操縦ハンドルに形成される衝突吸収手段が一体構造の 表面部（スキン）を持つポリウレタンフォーム或はＰｖＣ又はＰＰのような熱硬 化性合成樹脂の層で覆われ、運転手の区画と対面する層の部分に（よ、電気的及 び機械的回転変成器に接続された少なくとも１つのタッチスイッチが集積されて 、このスイッチがスポーク或は衝突吸収手段の近傍に配置された操縦ハンドルに 関する。[Detailed description of the invention] steering wheel for automobiles Technical field The present invention relates to a steering wheel for an automobile, and in particular to a rim and a sports steering wheel of the steering wheel. The collision absorbing means formed on the hub and the steering handle are integrally constructed. Polyurethane foam with a skin or thermoset such as PvC or PP The part of the layer facing the driver's compartment is covered with a layer of chemically resistant synthetic resin. and at least one touch switch connected to the mechanical rotary transformer. , this switch is located on the steering wheel located near the spoke or collision absorbing means. related.
背景技術 このような操縦ハンドルは、外観及び操作によって自動車の型式の特殊な特性を 強調することが望まれ、操縦／”１ンドルが運転手に所望の気分を提供しなけれ ばならず、彼らの評判を高めるためにもしばしば要求される。この気分は、種々 の制御機能が操縦ハンドルに協働することによって増加することができる。Background technology Such a steering wheel, by its appearance and operation, reflects the special characteristics of the vehicle type. It is desirable to emphasize that the steering/driver must provide the driver with the desired mood. Not only that, but they are also often required to enhance their reputation. This mood varies The control function of can be increased by cooperating with the steering handle.
しかし、ポリウレタンフォーム或はプラスチックの層に協働し、顕著に目視でき る複数のタッチスイッチが操縦／）ンドルの外観及び操作に悪影響を引き起こす 。However, it may work with the polyurethane foam or plastic layer, making it significantly less visible. Multiple touch switches may adversely affect the appearance and operation of the steering wheel. .
この外観を改良するためには、ＤＥ−Ｂ−１，９４８，６１５号公報に記載され 、衝突吸収用の変形できる本体で形成された操縦ハンドルが運転手の区画に対面 した変形できる本体の側に形成されている。スイッチの２つの接点の１つが警笛 用であり、これら接点の他及び２つのバネが操縦ハンドル自身に取付られている 。これらのバネの１つがアプローチに対面し、他が操縦ハンドルの変形本体のデ パーチャに対面して、変形本体が接点の遊びを維持するように弾性的に保持され ている。この場合、変形本体が電気的スイッチの回路閉塞部材として用いられて 、スイッチの部品を覆い隠している。In order to improve this appearance, the method described in DE-B-1,948,615 is required. , the control handle formed by a deformable body for collision absorption faces the driver's compartment. It is formed on the side of the deformable body. One of the two contacts on the switch is the horn In addition to these contacts, two springs are attached to the control handle itself. . One of these springs faces the approach and the other faces the deformed body of the steering handle. Facing the percha, the deformable body is held elastically to maintain contact play. ing. In this case, the deformed body is used as a circuit closing member of an electrical switch. , covering the parts of the switch.
ＤＥ−Ａ−３，２３６，２５７号公報から、操縦ハンドルのスポーク又はハブと 協働し、ポリウレタンフォームの層に埋設された金属／プラスチック複合材から なる平板状回路閉塞部品を、ポリウレタンフォームの層で外殻形成する操縦ハン ドルが公知である。金属層は、ケーブルによってスイッチのスリップリングに接 続され、接点に近接した穴を持ち、接点の遊びを維持するように配列された弾性 フオーム層が金属／プラスチック複合材からシートの金属層及び、操縦ハンドル のスポーク又はハブに形成された他の接点間に形成されている。この配列は、回 路閉塞部材の繰り返しの作動が時間が経過するに連れて相当の摩耗に繋がって、 回路閉塞部材の機能的信頼性を逆に損ねている。その上、回路閉塞部材は、ポリ ウレタンフォームが回りを囲み、操作中の気圧及び温度が位置の変化に影響する ので、オフ位置を信頼よく維持することができない。From DE-A-3,236,257, the spokes or hub of the steering wheel and From metal/plastic composites working together and embedded in a layer of polyurethane foam The steering handle consists of a flat circuit-blocking component with an outer shell made of a layer of polyurethane foam. Dollars are known. The metal layer is connected to the slip ring of the switch by a cable. elastics connected to each other, with holes close to the contacts, and arranged to maintain play in the contacts The foam layer is made from a metal/plastic composite to the metal layer of the sheet and the steering handle. between spokes or other contacts formed on the hub. This array is Repeated operation of the duct blockage member leads to considerable wear over time, On the contrary, the functional reliability of the circuit closing member is impaired. Moreover, the circuit closure member Urethane foam surrounds it, and atmospheric pressure and temperature during operation affect changes in position. So the off position cannot be maintained reliably.
発明の開示 本発明は、まず前述した型式の操縦ハンドルのために、信頼性よく作動でき、回 路閉塞部材を形成することなく、操縦ハンドルのポリウレタンフォームの層又は プラスチック層に容易に協働することができるタッチスイッチを提供することを 目的としている。Disclosure of invention The invention firstly provides for a control handle of the type described above, which is capable of reliable operation and rotation. A layer of polyurethane foam on the steering handle or To provide a touch switch that can easily cooperate with the plastic layer The purpose is
この目的は、操縦ハンドルに対面する接点シートと、この接点シートと直接接触 する半導体ポリマーシートと、この半導体ポリマーシートと接触し、運転手の区 画に対面する印刷導体に形成されたシートとからなるタッチスイッチによって達 成される。The purpose is to provide a contact sheet facing the control handle and a contact sheet that is in direct contact with this contact sheet. contact with the semiconducting polymer sheet and the driver's compartment. reached by a touch switch consisting of a sheet formed on a printed conductor facing the image. will be accomplished.
この半導体ポリマーシートは、操縦ハンドルの骨組みに取付られな接点シート及 び印刷導体に形成されたシート間の絶縁体を構成し、圧力が外側から例えば指に よってタッチスイッチに印加された時にのみ導体となる。印加された圧力が高く なればなるほど、半導体ポリマーシートの電導性が高くなる。この特性は、タッ チスイッチに現れる圧力と適合するように選択され、規格内で再現することがで きる。タッチスイッチを流れる電流は通常マイクロアンペアのオーダである。タ ッチスイッチは、印加される圧力に依存して内部抵抗が５ミリΩ以上から１にΩ に減少する。This semiconducting polymer sheet is used as a contact sheet and a It forms an insulator between the sheets formed on the printed conductor and allows pressure to be applied from the outside to, for example, a finger. Therefore, it becomes a conductor only when applied to the touch switch. the applied pressure is high The more conductive the semiconductor polymer sheet is, the higher the conductivity of the semiconductor polymer sheet becomes. This characteristic selected to match the pressure appearing on the switch and can be reproduced within specifications. Wear. The current flowing through a touch switch is typically on the order of microamperes. Ta Switches have an internal resistance that ranges from more than 5 milliohms to 1 ohm depending on the applied pressure. decreases to
タッチスイッチの活動接点及びスイッチするシートが常に相互に直接接触してい るので、スペーサの必要性がなく、タッチスイッチのシートがインタフェースで 外れる危険性がなく如何なる所望の形状を取ることができる。このタッチスイッ チは、可動部分を備えていないのでかなり長寿命を持っている。その上、タッチ スイッチは、１〜２ミリ秒の時間応答特性を持ち、それゆえ、可聴周波数又は高 調波での振動及び雑音に影響されない。The active contacts of a touch switch and the switching seat are always in direct contact with each other. This eliminates the need for spacers and allows the touch switch seat to be used as an interface. It can take any desired shape without the risk of coming off. This touch switch Since it has no moving parts, it has a fairly long lifespan. Besides, touch The switch has a time response characteristic of 1-2 milliseconds and therefore Unaffected by harmonic vibrations and noise.
本発明の更なる特徴によれば、タッチスイッチは、タッチスイッチがポリウレタ ンフォームの層又はプラスチック層に協働する被覆操作期間中に用いられる圧力 及び温度によって、手タッチスイッチの抵抗の変化が無視される電子比較器に接 続されている。According to a further feature of the invention, the touch switch is made of polyurethane. the pressure used during the coating operation on the foam layer or plastic layer; and temperature, the change in resistance of the hand touch switch is ignored. It is continued.
